Dear Sirs

Apologies for the delayed response.

You can indeed install our Rosewell GF-3H product on your existing Humbucker guitar.
Installation can be done using the provided screws and springs in the package, either with a
mounting or a pickguard.
However, please ensure to check the size of the product before installation.

RWRP stands for Reverse Wound, Reverse Polarized, commonly used as an abbreviation when
indicating the winding direction of the middle pickup of an S-S-S Stratocaster single-coil pickup setup.
It is used when the winding direction differs from that of the neck and bridge pickups.

If you have any questions, don’t hesitate to let us know.

Best regards,
paul – Production manager
